My wife Mary and I live in a college town with our two small girls. We have been married for almost 12 years. My wife taught school until we started our family.
About a year ago my wife began working for a local college's athletic department as a tutor. I constructed a room in our daylight basement for her tutoring work. We had a glass patio door installed so the students can enter the room without going through our house. The basement has a full lavatory adjoining the room and my workshop. Most of her tutoring is done in the evening. We are located about a mile from the college dormitories where most of her students reside.
A few months ago I happened to go into the basement bathroom, and I spied a condom, with its reservoir tip full of semen, lying in the toilet. I called my wife down to have a look. Her face reddened, and she turned and hurried upstairs. I didn't know what to think, but Mary soon returned and said that one of her students had brought his girlfriend to his tutoring session a couple nights earlier. She suggested that the couple had sex when she was upstairs putting our girls to bed. It sounded plausible.
A week or so later I had some reason to interrupt my wife during a tutoring session. When I walked in to her office she was standing alongside the student, and was rubbing his shaved head. It looked like his hand was under my wife's skirt. I wondered what was going on, but I pretended not to notice their activity. I was anxious to talk to her about something else, but I decided to wait until the student was gone.
Her tutoring was always scheduled to end at 9:30. The information I needed from her could not wait, so when I assumed her student had gone I went back down. What a surprise. She and the student were standing in the open doorway. He had his hands around her, and they were in a pretty close embrace. When the student, a big black athlete, saw me he immediately removed his arms and hurriedly walked away.
My wife gave me some feeble excuse that the young man was having some problems, and she was just trying to be a mother figure to him.
Most of the students walked the short mile from the college dorms to our house. Sometimes in bad weather my wife or I would drive them back. Well, one rainy night my wife drove that same black student back to his dorm. She was gone over a half hour for that short trip, and when she returned she was obviously excited. Her face was red, her hair was mussed up, and she did not even bother to talk to me before she rushed into the bedroom. I wondered whether that black guy had tried to molest her. She did not want to talk about it, but the next day she gave me some feeble excuse about the car stalling. I did not believe a word she said.
A couple weeks later I went to a basketball game in a nearby town with some friends. I did not plant to return until after eleven o'clock, but the game had to be canceled. I was back home before ten o'clock. The house was dark, and that was strange. My wife always stayed up until after ten, and her tutoring sessions always ended by 9:30. I walked into the bedroom, but she was not there. Just as I returned to the living room she came rushing up the stairs from her office, wearing her bathrobe, and seemingly out of breath. She said she had been preparing to go to bed when she recalled that she had not locked the patio door after her last student left. She hurried past me to get to our bedroom. In a minute she was in the shower.
I was beginning to suspect some hanky-panky. My wife almost always showered in the morning after I left for work. I went down to the basement to look around. More damning, a pair of jockey shorts was lying under a chair.
In bed with my wife I tried to feel her pussy, bu she kept her legs tight together and pushed my hands away, claiming to be very tired. Also, she was wearing panties under her nightgown. The only times she did that was during her period, and her period had ended about a week earlier. I did manage to feel her panties afer she was asleep, and I felt a pad inside them.
Mary uses a diaphragm for birth control, and as soon as she went into the bathroom in the morning I checked her night-stand. Her diaphragm was not there!
I did not say anything to my wife about my discovery, but it sure preyed on my mind. Who had screwed her? I never thought she would have the "hots" for a college boy at least 12 years her junior. For the next couple week I paid more attention to the students she was tutoring.
Most of the students were tutored in pairs. Most were also males. I did learn that one super jock always came alone, and usually he was there for more than the usual hour. Mary said that she often wondered how he ever made it through the college door, but he did excel in track and football. He was over six feet tall, very broad-shouldered and muscular. She tutored several of those big guys, but almost always in pairs. My wife talked so much about Eddie that I decided he was the one getting into my private playground.
I was sure my hunch was correct after what happened one Saturday. We occasionally hired a college student to do yard work, and Mary told me that morning she had one of her students coming that day to help out in the yard. We needed it, so I gave it no more thought.
When I came home from golfing I found her and Eddie eating lunch in the kitchen. She introduced us, and soon thereafter she drove him home. I checked her night stand and found her diaphragm was missing again. Later I found that someone had showered downstairs. My wife did tell me that Eddie had got so dirty that she let him shower downstairs.
In my job I had to spend an occasional night out of town. Several days after Eddoe worked in or yard - and undoubtedly on my wife - I was gone overnight. As soon as I returned late the next morning I checked for Mary's diaphragm. It was not in its box, but I suspected that it was in Mary's "box". When I checked again after dinner it was back in the night-stand.
I decided to set a trap, and perhaps catch Mary and Eddie having sex. Before I had to make another trip out of town a few weeks later I told Mary that I would spend the night away and take the early morning flight back. Instead I took a flight back so I was home by nine o'clock that same evening. I parked down the street where I could still watch my house.
Shortly after I had parked I saw her two students scheduled for that night leave. Then Eddie appeared and went to the front door. No students were allowed in the hose that way. As soon as our bedroom light went on I let myself in the patio door and sneaked into the hallway outside our bedroom. Someone was showering. The bedroom door was closed, so I could see nothing. After the shower stopped I could hear voices, my wife's and a man's, but I could make out very little.
I never realized our bed made any noise when we were having sex, but I soon heard the rhythmic sounds of our mattress straining under the heavy load bouncing up and down on it. It did not last too long. I guess he could not last any longer than I did.
